I tried to login to Diablo 3 and get a message stating wrong password.
I reset my password, but when I enter the password I remember, it says that I can't use the same password with existing password.
Then I change password to a different password anyway.
I tried to login again and the authenticator keeps giving the wrong number.
So I can't login to the battle net and then I can't ask support because only those who login can submit ticket.
In short, trying to login to my account gives error message authenticator code is wrong. Trying to login to Diablo 3 gives error message wrong password.
